CALIFORNIA 1 V PROCESS OF FORMING- MARKED SUBFAGING Application filed.July 18,

Our invention relates to improvements in process of forming markedsurfacing, and it consists in the steps hereinafter set forth.

An object of our invention is to provide a process in which markings ofvarious shades can be given to the composition, these markings extendingentirely through the thickness of the material. h

A further object of our invention is to proo vide a process of thecharacter described, in

which the markings are provided in the material before the latter isplaced upon the wall or floor to be surfaced, these markings beingchanged at the will of the operator after the material has been placedupon the floor, and while still in a plastic state.

, Other objects and advantages will appear in the followingspecification, and the novel features ofour invention will beparticularly 2O pointed out in the appended claims.

Our invention is illustrated diagrammatically in the accompanyingdrawing, forming a part of this application, in which I Figure 1 is atop plan view of a portion of the complete composition;

Figure 2 is a side elevation of the composition during one of theinitial stages of the forming thereof;

Figure 3 illustrates another step in the process;

Figure steps. I

In carrying out our invention we make use of powdered magnesite andmagnesium chloride solution. We mix these together in the proportions of100 pounds of magnesite to 125 pints of the solution, the solutionpreferably being at 23 B. ;'these two ingredients are stirred togetheruntil they are thoroughly mixed and when they are mixed they will form athin batter, which may be worked upon with atrowel. i

Asa filler we add 200 pounds of powdered calcium carbonate, or any othersuitable filler and we also add 10 pounds of magnesiumcarbonate, or anyother suitable filler having a better texture than the calcium carbonateand therefore having better. working possibilities. These two arestirred into the first mass until they are thoroughly 4 and Figure 5illustrate still other 1927. Serial No. 206,675.

mixed therein. The result is a mortar having a rather stiff consistency.We have also found that wood can beused as a filler, if a certaincharacteristic quality to the composition is desired. Other fillerswhich may be used are silica, talc, feldspar, et cetera. Before thecalcium carbonate and magnesium carbonate are added to the magnesite,and the magnesium chloride, a number of small quantities of the mixtureof magnesite no and the magnesium. chloride are set apart and they aretreated with various colors for providing the color lines in thecomplete mass which will be hereinafter described. One of the smallquantities of the first mix- 05 ture may be treated with iron oxide forforming a mass having a red color. Another quantity-may be treated withultramarine,

whichwill give a blue color to the mass so treated; a third may betreated inchromium oxide, whichgives' a green color; and a fourth may betreated with carbon, which will igive a black color. .It is obvious thatother colors may be mixed withother quantities of. the massformed fromthe magnesite, l5 and the magnesium chloride. We have set forth thesefew to show how the process is carried outin one of its forms.

The main mortar mixture consisting of the four ingredients set forth inthe first part so of the specification maybe tinted with a col,- or, ifdesired, so as to give a uniform color back-ground to theentirecomposition, or it may be left white, at the will of the operator.

This mortar is divided into a number of equal x v parts, the numberdepending upon the number of layers which the operator desires to use.Assume that five parts are formed. One

of these parts is spread out on a smooth sur face to make a layer, afterthe manner of a cake. This layer is then buttered with a thin layer ofone of the color mixtures, for example: the one treated with iron oxide.Reference to Figure 2 shows that the layer just mentioned is designatedby the numeral 1, while the layer of butter containing the iron oxide isdesignated by the reference numeral 2. A second quantity of the mortaris now placed upon the iron oxide, orred layer and is indicated by thereference numeral 3.

The top of this layer may now be buttered with the mass treated with theultramarine, as shown by reference numeral l. In this manner additionallayers 5, 6, and 7 are added one upon the other, and are separated bycolor layers 8, and 9, which are extremely thin relative to thethickness of layers 1, 3, 5, 6, and .7.

The mass is plastic and may be leveled down so as to spread over agreater area and of course be of less thickness than when the layerswere first piled one upon the other. It should be noted, however, thatthe color layer will not disappear through this step, but will be merelythinned out so as to provide substantially a pencil line betweena'djacentllayers.

The operator now doubles the number of color lines in the mass, bytaking the ends of the mass and folding them back upon themselves in'themannershown in Figure 3. "The end portions 1i) andli will meet eachother and will overlie the mid-portion 12. The first step is againrepeated until the entire mass spreads out and is of substantially thesame thickness as was formerly the case, before the first folding of themass took place. It will be noted, however, that in this instance thenumber of colorlines is exactly double to the number shown in Figure'12.

The mass is again folded upon itself for again doubling the color lines.These thinning and doubling over portions of the upon'other portions maybe continued three or .four times, if desired, or more, until thedesired number of color lines are formed in the composition. Thesecolor; lines will remain horizontal and will remain distinctly separatefrom each other, although the space separating adjacent icolor lines maybeextremely'smallj Thecomplete composition is shown in'Fi'gure 4 andthis composition will contain the'desired number of color lines and willalso be of the desired thiclmess.

In applying the composition 13 to the floor 14 a trowel, not shown, isused and *cuts through the composition along the. line. 15, see Figure4c. The portion I6 is removed from lire mass 13 and it will be notedthat the color lines 17 extend vertically with respect to the line 15,and therefore with respect to the trowel. The piece '16 is placed uponthe surface 14 so as'to cause the color lines 17 to extend entirelythrough the thickness of the composition. A number of similar pieces 16are severed from the mass 13 and are placed side by side upon the floor14 for forming a continuous surface, which has a number of verticallyextending color lines therein. We have described the mass as beingsliced .in a perpendicular line, as indicated by the numeral 15, but itisobvious that the slicing may be oblique, or in a horizontal manner,according to the will of the operator. 7 After the desired area has beencovered and someis again allowed to set so that the new matter added canbecome a part of the flooring.

'Thesnrface of the mass is again scraped, and

ifthesmoothness and the pattern has not yet beenobtained, a trowel maybe employed for scraping the surface, until the operator is satisfiedwith the results. The manner of applying the mass of slices determinesthe shape the various color lines will take in the complete work. Figure1 indicates the color lines 17 as extending in various directions andcauses the composition to closely simulate a piece of marble. Ingeneral, perpendicular's-li-cings which have been laid on with amovement in the direction of the color line,

will appear as veins, while horizontal ell-c ings will show asbl'otches, and oblique slicings will show the combination of veins andblotch-es. In this way, innumerable designs can be formed and thesedesigns can be of any color desired.

Although we have shown and described one embodiment of our invention, itis to be understood that the same is susceptible of various changes andwe reserve the right to employ such changes as may come within the scopeof the appended claims.

We claim:

1. "The method of making a surface imitatthat of veined natural stonewhich consists of laying out a layer of self-hardening material designedto give the appearance of the body of the surface, applying a thin layerof'sel'flh'ardenin'g material over the entire top surface of said layerdesigned to produce the veining, applying additional layers ofb'o'dy'material'and veining material alternately in such a manner thateach layer covers the entire top surface of the subjacent layer,

folding the ends of the stacked layers to getherover the center of thetop of themass, flattening out the mass and repeating the folding andflattening operations until the layers have been made quite thin toproduce the desired veining, slicing the mass transversely of th'elayers, applying the slices to the article to be surfaced and allowingthe slices to harden.

2. The method of making a variegated marbleized surface having coloredveins whi ch comprises making a mortar of relative stiffness, saidmortar being made of magnesite, magnesium chloride and a filler,spreadinga relatively thin layer of a color composition on said layer ofmortar, stacking successively and alternately layers, of mortar andcolored composition on top of one another, folding the stack togetherover the center of the top of the stack, flattening out the stack,

repeating the folding and flattening operations until the colored layershave been made extremely thin to produce the desired veining, slicingthe mass transversely of the layers, applying the slices on a foundationto form a surface, the veins of the slices running transversely to theplane of the surface, and allowing the surface to harden.
